Target mismatch criteria were met by 10/15 (66.7%) patients and did not correlate with reperfusion status or functional outcome. The hypoperfusion intensity ratio (HIR) was favorable in 11/15 patients and correlated with older age but not NIHSS, time to recanalization, or stroke etiology. Favorable HIR was associated with better functional outcome at 6 months (Pediatric Stroke Outcome Measure 1.0 [IQR 0.5–2.0] vs 2.0 [1.5–3.0], p = 0.026) and modified Rankin Scale 1.0 [0–1] vs 2.0 [1.5–3.5], p = 0.048) in this small sample.Discussion Automated perfusion imaging is feasible to obtain acutely in children and does not delay time to recanalization. Larger prospective studies are needed to determine biomarkers of favorable outcome in pediatric ischemic stroke and to establish core and penumbral thresholds in children.ADC=apparent diffusion coefficient; CASCADE=Childhood Arterial Ischemic Stroke Standardized Classification and Diagnostic Evaluation; DWI=diffusion-weighted imaging; HIR=hypoperfusion intensity ratio; IV=intravenous; IQR=interquartile range; LKW=last known well; LVO=large vessel occlusion; mRS=modified Rankin Scale; mTICI=modified Treatment in Cerebral Infarction; pNIHSS=pediatric National Institutes of Health Stroke Scale; PSOM=Pediatric Stroke Outcome Measure; ROC=receiver-operating characteristic; rCBF=relative cerebral blood flow; Tmax=time to maximum tissue residue function; TMM=Target Mismatch
